", "writing": "Beverly couldn't help but smile at herself as she gazed down at the canine before her. She adjusted her half-moon spectacles and cleared her throat and stood as tall and graceful as she could before speaking.\n\n\"Tell me, dear, do you know the know the origin of the term, 'estrus'?\"\n\nShar looked overwhelmed, either from the question or the desk she was sitting in. Perhaps it was neither, perhaps it was the schoolgirl uniform she was wearing that had the labrador blushing and wide-eyed with confusion. \"I, um, I don't know, miss Beverly.\"\n\nBeverly tsked and placed a fingertip to her own lips. \"Please called me 'Teacher', dearie. I don't get to dress like this often so I'd appreciate it if you went along with my little fantasy. <3\"\n\nBeverly was dressed like a horny teenager's fantasy teacher: sheer black stockings and garter belt with a miniskirt that barely covered her curvy rump along with a blouse too small for her to button closed. Instead it was tied in a knot and doing nothing to hide the pink outline of her nipples. Her hair was too short for a bun but her normal pair of spectacles completed the look, making Shar form a tent in her slightly oversized skirt; the uniform had been Beverly's when she was a teenager, from the pre-pubescent time when she had more hip than bust. It fit the canine well enough and added to the classroom-play while they were alone.\n\n\"Oestrus, meaning 'frenzy' or 'gadfly'. A word that purely describes sexual desire at the deepest, most primal level.\" Beverly paused to wink at her 'student'. \"You've felt such a thing more than once, Shar. The desire to mate, to be mated. In your current state you feel the need for something to be in you, a desire easily sated with a simple plug or toy. But the deep, nagging, unrelenting desire to penetrate, to plunge you thick shaft and thicker knot into another, to fill them with your hot seed... that is heat. It is desire, wild and reckless and hungry. It is this that your fiance is feeling right now.\"\n\nAt this Shar nodded despite her own blushing. Beverly could only imagine the strength of the trans girl's erection right now.\n\nBeverly continued. \"It is normal for a female to be struck with this for a length of time but in herms this can be different depending on the person. Kacey is leaning towards the center a bit; over the last twenty-four hours since admittance she has displayed a one in four chances of desire to top another. She has pounced at least two nurses while the other eight have taken turns topping her. She is particularly prone to begging to be filled or knotted or both. Your relationship seems to have cemented her favorite type of copulation... although there can be room for improvement.\"\n\n\"Pardon?\" At this Shar looked both surprised a bit hurt.\n\nBeverly reacted smoothly, walking over and seating herself on the desk, her skirt riding up to give Shar a full look at her rump and garterbelt, cow tail swishing lazily. \"Oh, this is no offense to you, dear, it's something I noticed. Really, I only want to help you with a little hesitation you seem to experience. One involving certain kinks that a certain... someone... might have spoiled for you.\"\n\nShar blushed and looked away; the bovine could almost hear the erection fading. \"You're talking about Kendra, aren't you?\" she muttered, a little frown on her cute muzzle.\n\n\"I am.\"\n\n\"Kendra... wasn't too careful after the transition. She made the simplest things terrifying...\"\n\n\"That is absolutely not how it is supposed to be.\" Beverly took Shar's paws in her hands and gave an encouraging squeeze. \"I will be glad to show you. <3\"\n\nShar balked. \"I-I'm not ready to be tied up-\"\n\nBeverly tittered. \"Oh, I don't mean you, silly. Class is in session and a good teacher teaches through effort and observation. You don't have to do a thing, dearie, just watch and take the lessons to heart.\"\n\nReleasing Shar's paws, Beverly gave a soft clap that sounded much louder than it should have in the small room. In truth, it was rather like an office complete with desk and whiteboard but with two doors, one on either side of the desk. Shar had been escorted in through the door to her right and from that same door stepped a third individual that she recognized at once. He was petite and fit but so feminine that at first glance one would think the equine that walked in to be a filly; it was Sasha, the stunningly cute colt whom Shar had spent an afternoon with during her 'boi-mode' adventure. He was nude save for sheer white stockings and lacey gloves. His mane was done up in a girly braid that kept it up and out of the way and a small white ribbon adorned the base of his tail; even his movements were girlish, with swaying hips and such innocent posture as his silky tail brushed against that cute rump. He blushed at the teacher and student before him and did a curtsy in Shar's direction before standing before Beverly, eyes fixed on only the bovine.\n\n\"Good girl, <3\" Beverly cooed at the colt and Shar saw the tremble in Sasha's hips at being praised; something she secretly understood. \"Shar, meet my assistant, Sasha. He is forbidden to talk without permission during my presentation. Excited whinnies don't count. <3\" Shar raised a paw and the bovine smiled. \"Yes?\"\n\n\"Uh, what are you presenting and why? What does this have to do with Kacey?\"\n\n\"Oh, this has much to do with Kacey and you as well! This is a brief lesson in the joy of bondage, a little something your fiance has a secret yearning for. You suffered a terrible first-impression when it came to bondage so we are here to show you how it's done right and how to enjoy it to the fullest. <3\"\n\nWithout another word, she reached into the desk and produced a familiar pair of items: a plain collar and leash. Shar blushed but kept silent as she watched Beverly approach and fasten the collar around Sasha's thin neck. It looked a little odd on an equine but that didn't seem to matter once the leash was clipped into place. One gentle tug downward and the colt dropped to all fours in a sitting position, blushing and looking mightily pleased with himself; the modest erection he was sporting betrayed his true emotions.\n\n\"This is one you are quite familiar with,\" Beverly began with a little flourish. \"The collar and leash is simple yet carries profound meaning in those wearing it and those holding said leash. I needn't espouse on this method long as your matrimonial collars speak for themselves but it's always good to start with the basics. And on that note we move onto another gentle yet very attractive layer: the gag. <3\"\n\nThis time Shar watched with confused interest as a red rubber ball was carefully fitted and strapped onto Sasha's muzzle, silencing him almost instantly. This was something Shar hadn't played too much with, not even with Kendra, yet there was no denying the return of her erection at the thought of putting that on Kacey. Beverly had made a slow show of it, coaxing and whispering little encouragements to her 'assistant' and even giving the red ball a tender little kiss before pulling away. It was so softcore yet so erotic at the same time.\n\n\"More a symbol of trust, the act of gagging your partner carries a deep meaning.\" Beverly let one hand gently caress Sasha's braided mane, his eyes closing and a soft sigh of desire escaping around the gag. \"With this, your partner cannot object, cannot use any safe-word. When they let themselves be gagged they are giving themselves entirely into your care thus silently proving their trust to be as strong as their love. It also helps if you need to have some quiet fun and your partner is a screamer. Incidentally, Kacey allowed herself to be gagged so we could remove the dildo and rather liked the experience. I highly recommend you two give it a try. <3\"\n\nThe lessons continued in this way, with Beverly showing and then explaining each action all while emphasizing the importance and symbolism behind each type of restraint. The bovine teacher kept the lesson relegated to the softer types of bondage, merely mentioning the more intense and restricting kinks with the promise of teaching Shar more should she and Kacey express any interest. It felt like forever as the demonstrations mounted, some involving toys and others involving only the slightest of actions to increase the pleasure one would feel. Deep in her heart Shar felt a bit of regret for being so hesitant to try; it was true, Kendra hadn't been the best partner but what's past is past, there was no reason she couldn't try again. Kacey was beyond wonderful and it was no secret her mothers were into some kinky things, so Shar shouldn't be so shy about it.\n\n\"I think that'll do for now. <3\"\n\nBeverly sighed, blushing and clearly aroused as she looked at the trussed up colt on her desk. Sasha was utterly helpless but looked extremely excited if his throbbing erection was any indicator. He whimpered and wiggled a little now and then, a muffled whinny of delight escaping the gag whenever he felt he couldn't move. Beverly's arousal was betraying her as well, her inner thighs slick with excitement and her stiff nipples threatening to burst from the undersized blouse. Shar couldn't deny the demonstration was beyond arousing for her, the tiny puddle of pre leaking from her member serving as proof.\n\n\"Well, I think it's time you two were reunited,\" the bovine announced, lightly fanning herself as she paced around the desk. \"Through the opposite door is one of our special 'heat suites', built for patients in estrus so they can safely ride out the urges. It's soundproofed so no need to worry about noise, but I do advise you to take some caution: Kacey's overwhelming desire is to be bred and she has become rather creative in her attempts. The desk here has some supplies you may find essential. I highly recommend a surplus of condoms in case she gets the drop on you; pull them over your knot, she won't have the patience to try and remove it. Don't be afraid to use some of what you learned as well, she might just like it even more. <3\"\n\nWithout another word, Beverly scooped the bound Sasha into her arms and carried him out through the door to the right, leaving Shar alone and aroused and a bit worried. The idea of breeding Kacey... her erection throbbed just at the thought but she knew not to be so hasty. Her seed was potent and they weren't even married yet. The wedding was coming closer and closer. Shar had to shake the thought away quickly, feeling her libido rocket at the mental image of a pregnant Kacey, beaming and glowing in her wedding gown. The canine had been so preoccupied with catching up with her family that she hadn't had time alone for over a week. A full week's worth of seed was stored in her aching orbs and it would only take one careless thought to prematurely go off. She had to focus and be prepared. In a flash, she had carefully stripped off the borrowed uniform and was rifling through the desk. The first item to use was the condom, a special type bearing the OmniMed emblem on the wrapper. It was tight and turned her black cock purple, knot and all, but it would keep her seed secure if she couldn't control herself.\n\n\"I wonder... \" she whispered to herself as she gazed at the array of bondage gear in the desk drawers. The earlier lessons were still fresh in her mind and a plan slowly began to form. One minute later and she had all the supplies she would need tucked under one arm. She took a deep breath and walked through the soundproofed door to her left. The room beyond was surprisingly cozy, furnished like a motel room complete with a huge king-sized bed in the center. On that bed was Kacey, out cold after masturbating herself to the point of exhaustion. Shar flushed, seeing that her fiance had been waiting for the canine and had indeed been plotting to get the jump on her beloved; a pair of fuzzy handcuffs lay on the floor and Kacey herself was dressed in a very alluring nurse uniform, playing directly to one of Shar's secret fetishes. The lessons from Beverly had taken too long and Kacey had lost patience, playing with her new favorite Shar-dildo and even re-knotting her pussy with it before fainting.\n\nShar set to work on binding the love of her life.\n\n\n[center]***[/center]\n\n\nWhen Kacey began to wake, she was surprised to find that she couldn't see. Or move. She was lying face down on the bed with her arms bound securely behind her back and her legs held open at the ankles. A spreader bar, maybe? And a blindfold? She shifted slightly and whimpered, feeling the toy she had replugged herself with still where she left it but felt a twinge of fear.\n\n\"Hello?\" she meekly called out. \"Beverly? D-Did you do this? I-It's not stuck this time, really, I-I was just playing.\"\n\nThere was a pause and then a familiar voice spoke.\n\n\"Morning, sleepyhead. <3\"\n\nKacey's heart leaped and then swelled with emotion. She recognized that voice!\n\n\"Shar?! <3\"\n\n\"Uh-huh. <3\" The bed shifted as someone climbed on, crawling to position themselves over Kacey. \"You've been a naughty girl while I was away.\"\n\n\"Huh? Ah! <3\" Kacey's confusion was lost in her surprised squeak as something hot and slick was placed between her helpless rump cheeks.\n\n\"You played with yourself so roughly without me,\" Shar said softly, leaving down to give the back of the bunny/panda's neck a nuzzle, eliciting another surprised squeak and whimper. \"I had to sniff you out, I really did. I followed your excitement all the way here and here you are, all dressed up for me. But you played with yourself too hard again and fainted. So naughty. <3\"\n\nKacey opened her mouth to protest but her words turned to a aroused moan when she felt something shift the toy inside of her. Someone was grabbing the base of her Shar-dildo again and slowly, carefully moving it around. Each time she tried to speak her words were reduced to mewls and moans and drawn out cries of pleasure as the toy was twisted, pulled, pushed until finally the pulling increased little by little. It wasn't as stuck this time and with a little popping sound, the silicone knot pulled free. She felt so empty without it in but the hot thing against her rump was still there and moving slowly. It took a moment to realize someone was hotdogging themselves on her.\n\n\"Sh-Shar...?\"\n\n\"I'm here, honey, I'm here, ,3\" came the whisper next to Kacey's head, soothing her a bit but her arousal was starting to peak again. That deep, unrelenting desire. \"Tell me what you want, love. <3\"\n\n\"B-Breed me... p-please... <3\" she whimpered and was surprised to feel something warm and wet press against her lips. Instinctively she opened her muzzle and let the object slide further until her lips bumped against a familiar knot. She ran her tongue all around a moment before pausing. This didn't taste like Shar's cock, it tasted like her own love honey. She was sucking on the Shar-dildo!\n\n\"Be patient, sweetie,\" Shar cooed as she moved again and lifted Kacey's hips, forcing the hybrid onto her knees with her upper body still prone on the bed. Kacey could feel the air on her privates and let out a startled sound when she felt warm breath against her sensitive opening.\n\n\"Mmph?!\"\n\n\"Sorry, sweetie, I'm just so thirsty for you... <3 <3 <3\" Shar breathed before planting her muzzle onto Kacey's crotch, using her canine tongue to full effect in the best way she knew. There was no resisting Shar's oral efforts and Kacey moaned and mewled around the silicone dildo in her muzzle, feeling like she would melt with that tongue stimulating all her spots at once. Shar wasn't exaggerating, she gulped down the copious juices that flowed from Kacey, drawing out orgasm after orgasm and reigniting the hybrid's burning passion for her fiance. Shar was greedily lapping at her pussy, nearly making Kacey faint all over again before slowing and finally stopping. With a long sigh she pulled her muzzle back, tongue sliding slowly free until Kacey could only feel the air on her super-sensitive privates. The dildo had long slipped from the hybrid's muzzle and she let out a weak mewl for her beloved.\n\n\"M-More... <3\" she whimpered and gasped as something hot and hard touched her ever so gently. It wasn't the toy this time, that was lying against her cheek. It was the real thing. The real Shar.\n\nThere was one good thrust and Kacey felt complete again, the whole shaft and knot slamming home into her pussy. All that time with the toy had gotten her so ready that the knot could easily pop in and out. That's exactly what Shar began to do, thrusting hard and deep, knot-fucking her fiance and drawing screams and cries of pure delight. Kacey couldn't stop cumming, it felt too good! Her tongue lolled out, the blindfold coming off with every jarring thrust home, panting and wailing as she gave herself over entirely to her heat. This was what she wanted, to be bred like this by her beloved. Her mind was starting to go blank as she came again and again. In the second before she fainted, Kacey felt Shar lean down to kiss her cheek and whisper in her ear:\n\n\"I love you, Kacey. <3\"\n\n\n[center]***[/center]\n\n\nWhen Beverly returned to check in on her patient she was wearing only her glasses, walking with a sway in her hips and looking very pleased. Her private time with Sasha had been exhilarating and she knew her little pet would be feeling the same when he woke up. The poor dear fainted away after Beverly finally let him cum after hours more of softcore bondage play; Beverly was ashamed to admit she had given in to her impulses but the boi looked so adorable with something in his muzzle.\n\n\"Oh?\" the bovine gasped softly when she entered the soundproofed room to find her favorite couple on the bed still. The initial reunion sex had concluded but the two were still playing in a way. Shar was seated at the foot of the bed with Kacey kneeling between her legs. The hybrid was still bound but naked save for the nurse cap on her head, arms behind her back and kneeling with a spreader bar between her ankles. Beverly could see the puddle of excitement her intern was making as she bobbed her head lazily between Shar's legs.\n\n\"Had quite some fun, did we? <3\" the bovine asked, surveying the room and training her eyes on the discarded purple condom on the nightstand. \"Shar, did you put one of the chastity condoms on? I was made to understood you hated such restrictions.\"\n\nShar blushed as she ran a paw over Kacey's bobbing head, stroking her monochrome hair lovingly. \"I do, but it's different when I do it myself,\" she admitted. \"We've talked and we do want to start a family together, but not like this. We'll do it on our terms.\" Her blush deepened and a bashful grin played on her muzzle. \"Also... I-I wanted to give Kacey a treat. <3\"\n\n\"A treat?\"\n\nKacey pulled her head back, letting Shar's black member slide from her muzzle with a lewd slurp. \"Uh-huh!\" she chirped, her fur a mess but looking happy as can be now that she was with her canine again. \"She's saved up a week's worth of cum all for me! <3\"\n\nBeverly felt herself blush a little as well, getting a look at how full Shar's orbs were before Kacey dove back onto that glistening black shaft. \"Well, well, I think I understand. Tell me, do you intended to paint her or feed her? <3\"\nShar gave a mischievous grin. \"She gets to pick. <3\"\n\nBeverly didn't have to wait long to see the result. After waiting so long to release, Shar's resistance was quite weak. Another few moments of dedicated fellatio from Kacey and the canine began to pant, looking down to see what Kacey would decide. When she refused to pull her head away Shar understood and held her down, whimpering and trembling as she came after so many days. Kacey was fantastic, spilling not a drop. Beverly felt her libido climb rapidly as she watched Kacey's flat tummy start to swell as she drank down load after load from her fiance. Finally Kacey pulled her head back, savoring every inch of Shar in her muzzle before swallowing the last mouthful and sighing contentedly. Beverly assisted the couple once more, helping Kacey onto the bed and showing how this type of spreader bar can collapse and become a normal set of restraints, locking Kacey's ankles together and allowing the bound bunny/panda to snuggle up with Shar on the bed. Her tummy looked quite full, like she were well along with a pregnancy.\n\n\"I think you'll make wonderful parents someday,\" she praised the pair, their blushing smiles warming her heart. \"I must return to my office but don't hesitate to call if you have any questions. This suite is booked solid until Kacey's heat has subsided and I can trust you two to take care. Do remember to stay hydrated and... oh, I nearly forgot. <3\"\n\nClimbing onto the bed, the matronly bovine leaned over to whisper something into one of Kacey's long ears, drawing a little giggle from the hybrid before climbing back off. Beverly gave a wave and excused herself, leaving the cuddling couple to themselves. Shar was a little curious and couldn't help but ask, \"What'd she say?\"\n\n\"Something she meant to tell me earlier,\" Kacey answered, a sly little smirk on her muzzle. \"She was telling me how to sate my desire to mount when it happens again.\"\n\n\"How's that?\"\n\n\"By saying the secret words to make you change back to a boi. <3\"\n\nShar blushed deeply but didn't object. If it was Kacey then she wouldn't mind, although she was still curious. \"Um, wh-what words?\"\n\n\"Oh, you know, some special words that you'll enjoy... but you gotta untie me beforehand. <3\"\n\nAfter a few moments Shar did exactly that, freeing her beloved and sitting up on the bed facing her. Kacey stood on her knees, her cum-filled tummy shifting a little as she leaned in to whisper in Shar's ear:\n[i]\n\"Pretty puppy, so cute and little, you're such a good boi. <3 <3 <3[/i]\"\n\nShar felt warmth spread through her body and closed her eyes as she shivered a little, opening her eyes to find that she was once more a he, as tall as Kacey. A feminine canine boi with long hair and a shy, timid demeanor. He blushed deeply, paws instinctively covering his chest and his less-prominent sheath. Kacey suppressed a delighted squeal, her own blush showing through her excitement as she hugged the boi-version of Shar.\n\n\"You're so cute! <3\" she gushed and tenderly kissed his ips, soothing his trembles a bit.\n\n\"Y-You can change me back, right?\" he asked timidly, his voice so much softer and even more girlish.\n\nKacey smiled and gave his cheek a lick, much like he would do to show affection. For Kacey it was playful and adorable but the act of licking a partner carried much more meaning for the canine... so much that it helped ease the remaining trembles. Gently she took his pas in her own and kissed him again, a soft, sensual kiss that calmed Shar. Soon the two were embracing on their knees, kissing and holding each other.\n\n\"Feel better?\" Kacey whispered after the kiss had broken.\n\n\"Uhhuh,\" came the soft response.\n\n\"I can change you back too with the right words, it's all part of the praise you like so much.\" The cum-filled tummy had begun to shrink little by little and Kacey ran a paw over some of the bondage equipment Shar had brought into the room before. \"I learned a lot about bondage early on, Mama and Auntie Mabel were happy to teach me.\"\n\nShar blushed but didn't object. In fact, a bashful smile could be seen on his muzzle. \"Y-You'll be gentle? <3\"\n\nKacey giggled and held up a plain collar, carefully fastening it around Shar's slender neck. \"Always, my cute puppy. <3\"\n\n\"Arf! <3 <3 <3\"\n\n", "writing_bbcode_parsed": "Beverly couldn't help but smile at herself as she gazed down at the canine before her. She adjusted her half-moon spectacles and cleared her throat and stood as tall and graceful as she could before speaking.

"Tell me, dear, do you know the know the origin of the term, 'estrus'?"

Shar looked overwhelmed, either from the question or the desk she was sitting in. Perhaps it was neither, perhaps it was the schoolgirl uniform she was wearing that had the labrador blushing and wide-eyed with confusion. "I, um, I don't know, miss Beverly."

Beverly tsked and placed a fingertip to her own lips. "Please called me 'Teacher', dearie. I don't get to dress like this often so I'd appreciate it if you went along with my little fantasy. <3"

Beverly was dressed like a horny teenager's fantasy teacher: sheer black stockings and garter belt with a miniskirt that barely covered her curvy rump along with a blouse too small for her to button closed. Instead it was tied in a knot and doing nothing to hide the pink outline of her nipples. Her hair was too short for a bun but her normal pair of spectacles completed the look, making Shar form a tent in her slightly oversized skirt; the uniform had been Beverly's when she was a teenager, from the pre-pubescent time when she had more hip than bust. It fit the canine well enough and added to the classroom-play while they were alone.

"Oestrus, meaning 'frenzy' or 'gadfly'. A word that purely describes sexual desire at the deepest, most primal level." Beverly paused to wink at her 'student'. "You've felt such a thing more than once, Shar. The desire to mate, to be mated. In your current state you feel the need for something to be in you, a desire easily sated with a simple plug or toy. But the deep, nagging, unrelenting desire to penetrate, to plunge you thick shaft and thicker knot into another, to fill them with your hot seed... that is heat. It is desire, wild and reckless and hungry. It is this that your fiance is feeling right now."

At this Shar nodded despite her own blushing. Beverly could only imagine the strength of the trans girl's erection right now.

Beverly continued. "It is normal for a female to be struck with this for a length of time but in herms this can be different depending on the person. Kacey is leaning towards the center a bit; over the last twenty-four hours since admittance she has displayed a one in four chances of desire to top another. She has pounced at least two nurses while the other eight have taken turns topping her. She is particularly prone to begging to be filled or knotted or both. Your relationship seems to have cemented her favorite type of copulation... although there can be room for improvement."

"Pardon?" At this Shar looked both surprised a bit hurt.

Beverly reacted smoothly, walking over and seating herself on the desk, her skirt riding up to give Shar a full look at her rump and garterbelt, cow tail swishing lazily. "Oh, this is no offense to you, dear, it's something I noticed. Really, I only want to help you with a little hesitation you seem to experience. One involving certain kinks that a certain... someone... might have spoiled for you."

Shar blushed and looked away; the bovine could almost hear the erection fading. "You're talking about Kendra, aren't you?" she muttered, a little frown on her cute muzzle.

"I am."

"Kendra... wasn't too careful after the transition. She made the simplest things terrifying..."

"That is absolutely not how it is supposed to be." Beverly took Shar's paws in her hands and gave an encouraging squeeze. "I will be glad to show you. <3"

Shar balked. "I-I'm not ready to be tied up-"

Beverly tittered. "Oh, I don't mean you, silly. Class is in session and a good teacher teaches through effort and observation. You don't have to do a thing, dearie, just watch and take the lessons to heart."

Releasing Shar's paws, Beverly gave a soft clap that sounded much louder than it should have in the small room. In truth, it was rather like an office complete with desk and whiteboard but with two doors, one on either side of the desk. Shar had been escorted in through the door to her right and from that same door stepped a third individual that she recognized at once. He was petite and fit but so feminine that at first glance one would think the equine that walked in to be a filly; it was Sasha, the stunningly cute colt whom Shar had spent an afternoon with during her 'boi-mode' adventure. He was nude save for sheer white stockings and lacey gloves. His mane was done up in a girly braid that kept it up and out of the way and a small white ribbon adorned the base of his tail; even his movements were girlish, with swaying hips and such innocent posture as his silky tail brushed against that cute rump. He blushed at the teacher and student before him and did a curtsy in Shar's direction before standing before Beverly, eyes fixed on only the bovine.

"Good girl, <3" Beverly cooed at the colt and Shar saw the tremble in Sasha's hips at being praised; something she secretly understood. "Shar, meet my assistant, Sasha. He is forbidden to talk without permission during my presentation. Excited whinnies don't count. <3" Shar raised a paw and the bovine smiled. "Yes?"

"Uh, what are you presenting and why? What does this have to do with Kacey?"

"Oh, this has much to do with Kacey and you as well! This is a brief lesson in the joy of bondage, a little something your fiance has a secret yearning for. You suffered a terrible first-impression when it came to bondage so we are here to show you how it's done right and how to enjoy it to the fullest. <3"

Without another word, she reached into the desk and produced a familiar pair of items: a plain collar and leash. Shar blushed but kept silent as she watched Beverly approach and fasten the collar around Sasha's thin neck. It looked a little odd on an equine but that didn't seem to matter once the leash was clipped into place. One gentle tug downward and the colt dropped to all fours in a sitting position, blushing and looking mightily pleased with himself; the modest erection he was sporting betrayed his true emotions.

"This is one you are quite familiar with," Beverly began with a little flourish. "The collar and leash is simple yet carries profound meaning in those wearing it and those holding said leash. I needn't espouse on this method long as your matrimonial collars speak for themselves but it's always good to start with the basics. And on that note we move onto another gentle yet very attractive layer: the gag. <3"

This time Shar watched with confused interest as a red rubber ball was carefully fitted and strapped onto Sasha's muzzle, silencing him almost instantly. This was something Shar hadn't played too much with, not even with Kendra, yet there was no denying the return of her erection at the thought of putting that on Kacey. Beverly had made a slow show of it, coaxing and whispering little encouragements to her 'assistant' and even giving the red ball a tender little kiss before pulling away. It was so softcore yet so erotic at the same time.

"More a symbol of trust, the act of gagging your partner carries a deep meaning." Beverly let one hand gently caress Sasha's braided mane, his eyes closing and a soft sigh of desire escaping around the gag. "With this, your partner cannot object, cannot use any safe-word. When they let themselves be gagged they are giving themselves entirely into your care thus silently proving their trust to be as strong as their love. It also helps if you need to have some quiet fun and your partner is a screamer. Incidentally, Kacey allowed herself to be gagged so we could remove the dildo and rather liked the experience. I highly recommend you two give it a try. <3"

The lessons continued in this way, with Beverly showing and then explaining each action all while emphasizing the importance and symbolism behind each type of restraint. The bovine teacher kept the lesson relegated to the softer types of bondage, merely mentioning the more intense and restricting kinks with the promise of teaching Shar more should she and Kacey express any interest. It felt like forever as the demonstrations mounted, some involving toys and others involving only the slightest of actions to increase the pleasure one would feel. Deep in her heart Shar felt a bit of regret for being so hesitant to try; it was true, Kendra hadn't been the best partner but what's past is past, there was no reason she couldn't try again. Kacey was beyond wonderful and it was no secret her mothers were into some kinky things, so Shar shouldn't be so shy about it.

"I think that'll do for now. <3"

Beverly sighed, blushing and clearly aroused as she looked at the trussed up colt on her desk. Sasha was utterly helpless but looked extremely excited if his throbbing erection was any indicator. He whimpered and wiggled a little now and then, a muffled whinny of delight escaping the gag whenever he felt he couldn't move. Beverly's arousal was betraying her as well, her inner thighs slick with excitement and her stiff nipples threatening to burst from the undersized blouse. Shar couldn't deny the demonstration was beyond arousing for her, the tiny puddle of pre leaking from her member serving as proof.

"Well, I think it's time you two were reunited," the bovine announced, lightly fanning herself as she paced around the desk. "Through the opposite door is one of our special 'heat suites', built for patients in estrus so they can safely ride out the urges. It's soundproofed so no need to worry about noise, but I do advise you to take some caution: Kacey's overwhelming desire is to be bred and she has become rather creative in her attempts. The desk here has some supplies you may find essential. I highly recommend a surplus of condoms in case she gets the drop on you; pull them over your knot, she won't have the patience to try and remove it. Don't be afraid to use some of what you learned as well, she might just like it even more. <3"

Without another word, Beverly scooped the bound Sasha into her arms and carried him out through the door to the right, leaving Shar alone and aroused and a bit worried. The idea of breeding Kacey... her erection throbbed just at the thought but she knew not to be so hasty. Her seed was potent and they weren't even married yet. The wedding was coming closer and closer. Shar had to shake the thought away quickly, feeling her libido rocket at the mental image of a pregnant Kacey, beaming and glowing in her wedding gown. The canine had been so preoccupied with catching up with her family that she hadn't had time alone for over a week. A full week's worth of seed was stored in her aching orbs and it would only take one careless thought to prematurely go off. She had to focus and be prepared. In a flash, she had carefully stripped off the borrowed uniform and was rifling through the desk. The first item to use was the condom, a special type bearing the OmniMed emblem on the wrapper. It was tight and turned her black cock purple, knot and all, but it would keep her seed secure if she couldn't control herself.

"I wonder... " she whispered to herself as she gazed at the array of bondage gear in the desk drawers. The earlier lessons were still fresh in her mind and a plan slowly began to form. One minute later and she had all the supplies she would need tucked under one arm. She took a deep breath and walked through the soundproofed door to her left. The room beyond was surprisingly cozy, furnished like a motel room complete with a huge king-sized bed in the center. On that bed was Kacey, out cold after masturbating herself to the point of exhaustion. Shar flushed, seeing that her fiance had been waiting for the canine and had indeed been plotting to get the jump on her beloved; a pair of fuzzy handcuffs lay on the floor and Kacey herself was dressed in a very alluring nurse uniform, playing directly to one of Shar's secret fetishes. The lessons from Beverly had taken too long and Kacey had lost patience, playing with her new favorite Shar-dildo and even re-knotting her pussy with it before fainting.

Shar set to work on binding the love of her life.


***



When Kacey began to wake, she was surprised to find that she couldn't see. Or move. She was lying face down on the bed with her arms bound securely behind her back and her legs held open at the ankles. A spreader bar, maybe? And a blindfold? She shifted slightly and whimpered, feeling the toy she had replugged herself with still where she left it but felt a twinge of fear.

"Hello?" she meekly called out. "Beverly? D-Did you do this? I-It's not stuck this time, really, I-I was just playing."

There was a pause and then a familiar voice spoke.

"Morning, sleepyhead. <3"

Kacey's heart leaped and then swelled with emotion. She recognized that voice!

"Shar?! <3"

"Uh-huh. <3" The bed shifted as someone climbed on, crawling to position themselves over Kacey. "You've been a naughty girl while I was away."

"Huh? Ah! <3" Kacey's confusion was lost in her surprised squeak as something hot and slick was placed between her helpless rump cheeks.

"You played with yourself so roughly without me," Shar said softly, leaving down to give the back of the bunny/panda's neck a nuzzle, eliciting another surprised squeak and whimper. "I had to sniff you out, I really did. I followed your excitement all the way here and here you are, all dressed up for me. But you played with yourself too hard again and fainted. So naughty. <3"

Kacey opened her mouth to protest but her words turned to a aroused moan when she felt something shift the toy inside of her. Someone was grabbing the base of her Shar-dildo again and slowly, carefully moving it around. Each time she tried to speak her words were reduced to mewls and moans and drawn out cries of pleasure as the toy was twisted, pulled, pushed until finally the pulling increased little by little. It wasn't as stuck this time and with a little popping sound, the silicone knot pulled free. She felt so empty without it in but the hot thing against her rump was still there and moving slowly. It took a moment to realize someone was hotdogging themselves on her.

"Sh-Shar...?"

"I'm here, honey, I'm here, ,3" came the whisper next to Kacey's head, soothing her a bit but her arousal was starting to peak again. That deep, unrelenting desire. "Tell me what you want, love. <3"

"B-Breed me... p-please... <3" she whimpered and was surprised to feel something warm and wet press against her lips. Instinctively she opened her muzzle and let the object slide further until her lips bumped against a familiar knot. She ran her tongue all around a moment before pausing. This didn't taste like Shar's cock, it tasted like her own love honey. She was sucking on the Shar-dildo!

"Be patient, sweetie," Shar cooed as she moved again and lifted Kacey's hips, forcing the hybrid onto her knees with her upper body still prone on the bed. Kacey could feel the air on her privates and let out a startled sound when she felt warm breath against her sensitive opening.

"Mmph?!"

"Sorry, sweetie, I'm just so thirsty for you... <3 <3 <3" Shar breathed before planting her muzzle onto Kacey's crotch, using her canine tongue to full effect in the best way she knew. There was no resisting Shar's oral efforts and Kacey moaned and mewled around the silicone dildo in her muzzle, feeling like she would melt with that tongue stimulating all her spots at once. Shar wasn't exaggerating, she gulped down the copious juices that flowed from Kacey, drawing out orgasm after orgasm and reigniting the hybrid's burning passion for her fiance. Shar was greedily lapping at her pussy, nearly making Kacey faint all over again before slowing and finally stopping. With a long sigh she pulled her muzzle back, tongue sliding slowly free until Kacey could only feel the air on her super-sensitive privates. The dildo had long slipped from the hybrid's muzzle and she let out a weak mewl for her beloved.

"M-More... <3" she whimpered and gasped as something hot and hard touched her ever so gently. It wasn't the toy this time, that was lying against her cheek. It was the real thing. The real Shar.

There was one good thrust and Kacey felt complete again, the whole shaft and knot slamming home into her pussy. All that time with the toy had gotten her so ready that the knot could easily pop in and out. That's exactly what Shar began to do, thrusting hard and deep, knot-fucking her fiance and drawing screams and cries of pure delight. Kacey couldn't stop cumming, it felt too good! Her tongue lolled out, the blindfold coming off with every jarring thrust home, panting and wailing as she gave herself over entirely to her heat. This was what she wanted, to be bred like this by her beloved. Her mind was starting to go blank as she came again and again. In the second before she fainted, Kacey felt Shar lean down to kiss her cheek and whisper in her ear:

"I love you, Kacey. <3"


***



When Beverly returned to check in on her patient she was wearing only her glasses, walking with a sway in her hips and looking very pleased. Her private time with Sasha had been exhilarating and she knew her little pet would be feeling the same when he woke up. The poor dear fainted away after Beverly finally let him cum after hours more of softcore bondage play; Beverly was ashamed to admit she had given in to her impulses but the boi looked so adorable with something in his muzzle.

"Oh?" the bovine gasped softly when she entered the soundproofed room to find her favorite couple on the bed still. The initial reunion sex had concluded but the two were still playing in a way. Shar was seated at the foot of the bed with Kacey kneeling between her legs. The hybrid was still bound but naked save for the nurse cap on her head, arms behind her back and kneeling with a spreader bar between her ankles. Beverly could see the puddle of excitement her intern was making as she bobbed her head lazily between Shar's legs.

"Had quite some fun, did we? <3" the bovine asked, surveying the room and training her eyes on the discarded purple condom on the nightstand. "Shar, did you put one of the chastity condoms on? I was made to understood you hated such restrictions."

Shar blushed as she ran a paw over Kacey's bobbing head, stroking her monochrome hair lovingly. "I do, but it's different when I do it myself," she admitted. "We've talked and we do want to start a family together, but not like this. We'll do it on our terms." Her blush deepened and a bashful grin played on her muzzle. "Also... I-I wanted to give Kacey a treat. <3"

"A treat?"

Kacey pulled her head back, letting Shar's black member slide from her muzzle with a lewd slurp. "Uh-huh!" she chirped, her fur a mess but looking happy as can be now that she was with her canine again. "She's saved up a week's worth of cum all for me! <3"

Beverly felt herself blush a little as well, getting a look at how full Shar's orbs were before Kacey dove back onto that glistening black shaft. "Well, well, I think I understand. Tell me, do you intended to paint her or feed her? <3"
Shar gave a mischievous grin. "She gets to pick. <3"

Beverly didn't have to wait long to see the result. After waiting so long to release, Shar's resistance was quite weak. Another few moments of dedicated fellatio from Kacey and the canine began to pant, looking down to see what Kacey would decide. When she refused to pull her head away Shar understood and held her down, whimpering and trembling as she came after so many days. Kacey was fantastic, spilling not a drop. Beverly felt her libido climb rapidly as she watched Kacey's flat tummy start to swell as she drank down load after load from her fiance. Finally Kacey pulled her head back, savoring every inch of Shar in her muzzle before swallowing the last mouthful and sighing contentedly. Beverly assisted the couple once more, helping Kacey onto the bed and showing how this type of spreader bar can collapse and become a normal set of restraints, locking Kacey's ankles together and allowing the bound bunny/panda to snuggle up with Shar on the bed. Her tummy looked quite full, like she were well along with a pregnancy.

"I think you'll make wonderful parents someday," she praised the pair, their blushing smiles warming her heart. "I must return to my office but don't hesitate to call if you have any questions. This suite is booked solid until Kacey's heat has subsided and I can trust you two to take care. Do remember to stay hydrated and... oh, I nearly forgot. <3"

Climbing onto the bed, the matronly bovine leaned over to whisper something into one of Kacey's long ears, drawing a little giggle from the hybrid before climbing back off. Beverly gave a wave and excused herself, leaving the cuddling couple to themselves. Shar was a little curious and couldn't help but ask, "What'd she say?"

"Something she meant to tell me earlier," Kacey answered, a sly little smirk on her muzzle. "She was telling me how to sate my desire to mount when it happens again."

"How's that?"

"By saying the secret words to make you change back to a boi. <3"

Shar blushed deeply but didn't object. If it was Kacey then she wouldn't mind, although she was still curious. "Um, wh-what words?"

"Oh, you know, some special words that you'll enjoy... but you gotta untie me beforehand. <3"

After a few moments Shar did exactly that, freeing her beloved and sitting up on the bed facing her. Kacey stood on her knees, her cum-filled tummy shifting a little as she leaned in to whisper in Shar's ear:

"Pretty puppy, so cute and little, you're such a good boi. <3 <3 <3"

Shar felt warmth spread through her body and closed her eyes as she shivered a little, opening her eyes to find that she was once more a he, as tall as Kacey. A feminine canine boi with long hair and a shy, timid demeanor. He blushed deeply, paws instinctively covering his chest and his less-prominent sheath. Kacey suppressed a delighted squeal, her own blush showing through her excitement as she hugged the boi-version of Shar.

"You're so cute! <3" she gushed and tenderly kissed his ips, soothing his trembles a bit.

"Y-You can change me back, right?" he asked timidly, his voice so much softer and even more girlish.

Kacey smiled and gave his cheek a lick, much like he would do to show affection. For Kacey it was playful and adorable but the act of licking a partner carried much more meaning for the canine... so much that it helped ease the remaining trembles. Gently she took his pas in her own and kissed him again, a soft, sensual kiss that calmed Shar. Soon the two were embracing on their knees, kissing and holding each other.

"Feel better?" Kacey whispered after the kiss had broken.

"Uhhuh," came the soft response.

"I can change you back too with the right words, it's all part of the praise you like so much." The cum-filled tummy had begun to shrink little by little and Kacey ran a paw over some of the bondage equipment Shar had brought into the room before. "I learned a lot about bondage early on, Mama and Auntie Mabel were happy to teach me."

Shar blushed but didn't object. In fact, a bashful smile could be seen on his muzzle. "Y-You'll be gentle? <3"

Kacey giggled and held up a plain collar, carefully fastening it around Shar's slender neck. "Always, my cute puppy. <3"

"Arf! <3 <3 <3"
